Information-Oriented Trustworthiness Evaluation in Vehicular Ad-hoc Networks

摘要: In Vehicular Ad-Hoc Networks (VANETs), applications are typically realized by forwarding and exchanging messages among vehicles. The integrity trustworthiness of directly impacts the quality applications. Though there have been extensive works on authentication protocols in VANETs, can only certify message origin but cannot guarantee that identity holders will send truthful accurate messages. Therefore, this paper, we propose a novel trust model to evaluate content received from other is built based various factors such as similarity, conflict route similarity. Trustworthiness be evaluated at individual vehicle level not introduce any additional architectural assumptions. We conducted experiments results indicate both efficiency effectiveness proposed approach.
